🛡️ Repulsor

Repulsor is a Forge mod for Minecraft 1.20.1 that adds a single admin-style item: hold it in your off-hand and nothing can get close to you. Crouch, and everything comes to you instead.

It creates a protective bubble around the player, repelling nearby entities, cancelling fall damage, and pulling entities in on demand, all marked by a glowing ring on the ground.

✨ Features

🛡️ Repel Field

• While the item is in your off-hand, entities are pushed away so they can't get within 4 blocks of you.
• Hostile mobs, passive mobs and other players are all affected.
• Projectiles fired by other entities are deflected away from you.

🌀 Pull Mode

• Crouch (Shift) and the field flips: entities within 4 blocks are pulled toward you instead.
• Entities stop a short distance from you (about 1.5 blocks, and about 2.2 for boats and minecarts) so they don't pile on top of you.
• Living entities can climb small ledges and holes while being pulled.

🪶 No Fall Damage

• You take no fall damage while holding the item in your off-hand.

🔵 Visual Ring

• A ring on the ground marks the edge of the field and follows you as you move.
• Blue soul flames rise from the ground while repelling.
• Purple mist flows toward you while pulling.
• Other players nearby can see your ring too.

👑 Operators Only

• The effects only work for players with operator permissions (permission level 2 or higher).
• In singleplayer, cheats must be enabled.

💬 Detailed Tooltip

• Hover over the item to see a short description.
• Hold Shift in the inventory to see what pull mode does.
• Available in English and Spanish.

🚫 What It Doesn't Affect

The field ignores:

• 📦 Dropped items and ⭐ experience orbs
• 🖼️ Item frames and paintings, and 🧍 armor stands
• 🐺 Your own tamed pets, your tamed horses, donkeys, mules and llamas, and any animal you are holding on a leash
• 🚤 Boats that are empty or that you are steering, and anything you are riding
• 🏹 Projectiles you shot yourself
• 👻 Spectators

Projectiles fired by other entities are always deflected, even in pull mode.
